I see no reason to have the Phoenix be involved here. Or Jean for that matter unless they start with a complete ALT reality non X1,2 and 3 related. Otherwise Keep Jean and Scott dead till the time problems are resolved. No need to resurrect characters just to kill them on screen again.

Agreed. If its post X3, there is zero reason to do any of that with Jean and Scott.
